<p><a href="https://tools.ietf.org/html/rfc4880#section-5.13">RFC4880 5.13</a>:
The Symmetrically Encrypted Integrity Protected Data packet is
a variant of the Symmetrically Encrypted Data packet. It is a new feature
created for OpenPGP that addresses the problem of detecting a modification to
encrypted data. It is used in combination with a Modification Detection Code
packet.</p></div>
